PROBLEM TO BE SOLVED: To improve reliability in co-occurrence to be used for generating system response sentences by generating the co-occurrence through the use of a categorem in the system response sentence being correct information and a categorem in a recognition result. SOLUTION: A voice interactive device of the embodiment includes: voice recognition means for recognizing the vocalization of a user with respect to a first system response sentence; morphological analysis means for performing the morphological analysis of a recognition result which is obtained by the voice recognition means; co-occurrence generation means for generating the co-occurrence of a categorem in the recognition result acquired by the morphological analysis means and a categorem in the first system response sentence; a co-occurrence dictionary for storing the co-occurrence of the categorems and the co-occurrence score of the co-occurrence; co-occurrence score imparting means for imparting the co-occurrence score to the co-occurrence generated by the co-occurrence generation means by using the co-occurrence dictionary; and response sentence generation means for generating a second system response sentence through the use of the co-occurrence score imparted by the co-occurrence score imparting means.
